Lignicolous Macro Fungi from Gujarat, India Available online at www.worldscientificnews.com WSN 45(2) (2016) 307-330 EISSN 2392-2192 Lignicolous Macro Fungi from Gujarat, India Praveen Kumar Nagadesi1,*, Arun Arya2 1Department of Botany, Andhra Loyola College, Vijayawada - 520008, Andhra Pradesh, India 2Department of Botany, Faculty of Science, The Maharaja Sayajirao University of Baroda, Vadodara - 390002, Gujarat, India *E-mail address: [email protected] ABSTRACT The state of Gujarat is well known for its contrasting eco-regions such as moist deciduous forests and deserts. The documentation of Lignicolous fungal diversity of Gujarat state was started in 19th century by different scientist. Detailed fungal diversity study was started in 2003 from different parts of Gujarat to identify the lignicolous fungi that destroy wood logs in different forests. During these studies we noticed a great lacuna in fungal diversity of lignicolous fungi occurring in Gujarat. Here we provide, for the first time, lignicolous fungal diversity from timbers of Gujarat state. The survey revealed that the economically important woods present in Gujarat were 14 and locally available common woods were seven. A total of 69 species Lignicolous macro fungi belong to 15 families and 30 general. These wood deteriorating fungi were belonging to the families Xylariaceae, Agaricaceae Coprinaceae, Pleurotaceae Auricularreae, Bondarzewiaceae Ganodermataceae, Shizophyllaceae, Stecherinaceae, Hymenochaetaceae, Lachnocladiaceae, Schizoporaceae, Fomitopsidaceae, Polyporaceae Stereaceae. All the lignicolous fungi were new to Gujarat, India. For the first time Agaricus bisporus (Lange) Sing. Agaricus silvaticus Schaeff. Coprinus plicatilis (Fr.) Fr. Pleurotus pulmonarius (Fries) Quélet, belonging to Agaricales were reported from Gujarat, India. The commonly observed lignicolous fungi on woods belongs to Basidiomycota and Ascomycota were Schizophyllum commune, Flavodon flavus, Ganoderma lucidum, Daldinia concentric, Xylaria polymorpha. Keywords: Macrofungi; Lignicolous, Gujarat; Xylariaceae; Agaricales World Scientific News 45(2) (2016) 307-330 1. INTRODUCTION The occurrence and distribution of different Aphyllophoroid Basidiomycetes depends on the type of wood, availability of moisture, temperature, and sun light. It is interesting to note that history of Aphyllophorales is quite old in India. Important contributors are Bose, Sundararaman and Marudarajan, Bakshi and Thind among others. Bose [1] gave a comprehensive account on Indian Polypores collected from Bengal in a series of papers. Sundararaman and Marudarajan [2] also reported several polypores from Madras. Sarbhoy et al [3] listed more than 500 Aphyllophorales. Bakshi [4] published a book on Indian Polyporaceae and Sharma [5] on Hymenochaetaceae of India. Thind [6] explored of mycoflora in Himalayas. He put forth the tissue concept for Indian species of polypore as proposed by Corner. According to available record, Bakshi [4] also reported Polyporus luteo-umbrinus Romell on ground attached to buried wood or root and dead fallen Heritiera minor in Baroda, Gujarat. Wood deteriorating fungi were first collected in Gujarat state in 1992 by S. D. Sabnis and later by Arya in 2004. Sabnis reported Polyporus sp. From Sardar Sarovar in Gujarat. and Arya [7] reported 7 species of fungi from Schoolpaneshwar Wildlife Sanctuary, Gujarat i. e. Phallus impudicus L., Cyanthus striatus (Schw.) de Toni, Ganoderma lucidum (Fr.) Ryv., Lenzites sterioides (Fr.) Ryv., Phellinus nilgheriensis (Mont) Cunn, Trametes cingulata Fr, and T. Varians Van der Bij. The Trametes varians and Lenzites sterioides are new reports to India. Arya et al. [8] reported that Lenzites sterioides was recorded for the first time on T. grandis. Two other polypores Navisporus floccosus and Coriouls aspera were reported for the first time from India. Nagadesi & Arya [9] reported Aurificaria indica var. leucocephala var. nov, and Microporus affinis var. glabriceps var. nov. were described and four species, Fomitopsis cupreorosea, Ganoderma curtisii, Microporus alboater and Phellinus shaferi from Ratanmahal Wildlife Sanctuary (RWLS), Gujarat were new reports for India. Thirty species of lignicolous fungi belonging to Ascomycetes and Basidiomycete are reported from the Ratanmahal Wildlife Sanctuary, Gujarat, India. The new species are Coriolus versicolor, Coriolopsis gallica, Daedalea quercina, F. resupinate, D. unicplor var. hydnoidea, Fomitopsis rosea, Hypodontia comptopsis and Lenzites betulina. F. varigatum is reported for the first time from India. All the species are new to Gujarat, India [10]. Rotting of Peltophorum ferrugineum (Decne.) Benth. living trees by pathogenic lignicolous fungi like Flavodon flavus (Klotz.) Ryv., Gloeophyllum sepiarium (Fr.) Karst., Ganoderma applanatum (Pers.) Pat. and Schizophyllum commune Fr. was describe [11]. Taxonomic studies of the genus Phellinus had been extensively done throughout the world by different mycologist [12,13]. P. rubriporus (Phellinus torulosus) was selected by Donk [14] as generic nomenclature type. Then the concept of Phellinus has remained stable. In India Phellinus was studied by Bagchee [15] and Sharma [16]. Fifty three species have been already reported from India [16]. Eighteen species have been reported from Kerala [17]. Lignicolous fungi play a significant role in destruction of forest flora especially wood, litter and living trees. A few species of Phellinus was reported from Gujarat i.e. Phellinus nilgheriensis (Mont.) Cunn [7]. Rotting of Peltophorum ferrugineum (Decne.) Benth. living trees by pathogenic lignicolous fungi like Phellinus badius (Berk.: Cke) Cunn., P. robustus (Karst.) Bourd. & Galz., P. pectinatus (Kl.) Quel., P. hoehnelii (Bres.) Ryv., P. conchatus (Pers.: Fr.) Quel., P. pachyphloeus (Pat.) Pat., P. rhabarbarinus (Berk.) Cunn., P. setulosus -308- World Scientific News 45(2) (2016) 307-330 (Llyod) Imaz., and P. caryophyllii (Racib.) Cunn. was describe [11]. For the first time all lignicolous fungi were recorded from Rajpipla, Gujarat, India. It was interesting to note that in Vadia palace, Rajpipla there are approximately 100 P. ferrugineum trees, out of which 69 plants were infected with pathogenic lignicolous fungi. In Arboretum of Botany Department, M.S. University of Baroda was surveyed, 10 plants were present, and out of that 7 plants were infected. Except P. setulosus which was already reported on P. ferrugineum all other Phellinus spp are new host records [11]. Timer decay is caused by primarily enzymatic activities of microorganisms. For the first time fungal diversity of timber degrading fungi was studied in Gujarat, India. Timber Degrading Fungi belonging to Aphyllophorales are economically important as many of these cause serious damage in sawmills of Gujarat. To find out the association of the timber degrading fungi and timber decay problems in sawmills a survey was conducted during 2007 to 2011 in different sawmills of 5 districts of Gujarat i.e. Vadodara, Ahmedabad, Bharuch, Rajkot and Jamnagar. teak wood present in sawmills was infected with 14 types of fungi in which Lenzites sterioides and Trametes versicolor damaged the wood severely was reported for the first time [18]. In all 94 sawmills were surveyed, the 28 sawmills were from Vadodara, 29 from Ahmedabad, 12 from Bharuch, 21 from Rajkot and 4 from Jamnagar. Out of 94 sawmills surveyed, 84 sawmills were having timber rotting fungi associated with wood. Maximum fifteen and thirteen fungal species were observed in saw mills of Chhani road, followed by 11 in Station road, 7 in Dhabhoi road and 6 in Harni, Vadodara. Fours woods uninfected are Beyo, Marinty, Ash, and Arjun. Fourteen different types of fungi were found associated with teak, followed by seven in pinus, madhuca, Acacia nilotica, six in babul, neem, four in tamarind, Pithacoelobium and three in mango, Eucalyptus, African Mahagoni, Kapoor, Peltophoram rouxburghii, Derris pinnata wood respectively. The commonly observed timber decaying fungi were S. commune, F. flavus and G. lucidum belonging to Basidiomycota. Ascomycota members included were D. concentrica and X. polymorpha [18]. A wood decay fungus was defined based on the zone of tree that invades. N. floccosus causing heart rot was recorded in living trees of A. excelsa for the first time. The cultural characters of N. floccosus were described for the first time [19]. Fungi may cause internal decay, cankers, loosening of tissue and cell walls result into weak forks in the trunk and large branches. Tree rot may be associated with root decay, damage to foliage and fruits. Wood decay fungi isolated from Tamarindus indica were D. concentrica, S. commune, F. flavus, Irpex hydnoides, and P. fastuosus, in which D. concentrica causing canker rot is reported for the first time from India and F. flavus and I. hydnoides P. fastuosus are recorded for the first time on T. indica wood causing white rot. During canker rot, formation of bark canker and extensive internal decay of wood was observed; as a result the tree growing in the M.S. University campus became structurally unstable and broken off at the canker face. Early detection and removal of such hazardous branches of trees is advocated to avoid loss of life and property [20]. 2. MATERIALS AND METHODS 2. 1.

However, the rate of forest loss greatly exceeds the rate of species documentation and this increases the risk of losing macrofungi diversity to extinction. A field study was carried out in Kereita, Kikuyu Escarpment Forest, southern part of Aberdare range forest to determine effect of indigenous forest conversion to plantation forest on diversity of macrofungi. Macrofungi diversity was assessed in a 22 year old Pinus patula (Pine) plantation and a pristine indigenous forest during dry (short rains, December, 2014) and wet (long rains, May, 2015) seasons.

J. KEIZER IN RIVERS STATE, NIGERIA. Dimkpa, S. O. N. and Orikoha, E. C. Department of Crop/Soil Science, Rivers State University, Port Harcourt, P.M.B 5080, Rivers State, Nigeria. ABSTRACT: This research on the isolated and morphologically identification of fungi and bacteria in soils naturally colonized by wild mushroom Agaricus silverticus was carried out in the crop protection laboratory at the Rivers State University. Soil samples were collected from 4 different locations in Ogwe, Ukwa West Local Government Area, Abia State, Nigeria: 3 sample sites from Obiahia kindred the mushroom colonized soils in its natural habitats and the fourth a control plot from Obiawom kindred where mushroom was not found. The experimental result significantly (P˂0.05) revealed the presence of six fungi genera: four mushroom inhibiting microbes namely Penicillium spp., Sclerotium spp., Mucor spp. and Aspergillus spp. in decreasing order from the control sites where Agaricus mushroom was not found and two other benefiting fungi genara: Yeast and Fusarium spp. from the Agaricus Mushroom colonized soils. However, fairly insignificant number (P>0.05) of Penicillium spp. was also recorded in site three of the Agaricus colonized soil habitat though overshadowed by the very high presence of Yeast. Similarly, six bacterial genera (Bacillus spp, Proteus spp, Micrococcus spp, Streptococcus spp, Staphylococcus spp and Pseudomonas spp) were isolated and morphologically identified.

  • A Preliminary Checklist of Arizona Macrofungi
    A PRELIMINARY CHECKLIST OF ARIZONA MACROFUNGI Scott T. Bates School of Life Sciences Arizona State University PO Box 874601 Tempe, AZ 85287-4601 ABSTRACT A checklist of 1290 species of nonlichenized ascomycetaceous, basidiomycetaceous, and zygomycetaceous macrofungi is presented for the state of Arizona. The checklist was compiled from records of Arizona fungi in scientific publications or herbarium databases. Additional records were obtained from a physical search of herbarium specimens in the University of Arizona’s Robert L. Gilbertson Mycological Herbarium and of the author’s personal herbarium. This publication represents the first comprehensive checklist of macrofungi for Arizona. In all probability, the checklist is far from complete as new species await discovery and some of the species listed are in need of taxonomic revision. The data presented here serve as a baseline for future studies related to fungal biodiversity in Arizona and can contribute to state or national inventories of biota. INTRODUCTION Arizona is a state noted for the diversity of its biotic communities (Brown 1994). Boreal forests found at high altitudes, the ‘Sky Islands’ prevalent in the southern parts of the state, and ponderosa pine (Pinus ponderosa P.& C. Lawson) forests that are widespread in Arizona, all provide rich habitats that sustain numerous species of macrofungi. Even xeric biomes, such as desertscrub and semidesert- grasslands, support a unique mycota, which include rare species such as Itajahya galericulata A. Møller (Long & Stouffer 1943b, Fig. 2c). Although checklists for some groups of fungi present in the state have been published previously (e.g., Gilbertson & Budington 1970, Gilbertson et al. 1974, Gilbertson & Bigelow 1998, Fogel & States 2002), this checklist represents the first comprehensive listing of all macrofungi in the kingdom Eumycota (Fungi) that are known from Arizona.

    Fungus and Lichen Genera in the NEMF Database Taxonomic hierarchy: phyllum > class (-etes) > order (-ales) > family (-ceae) > genus. Total number of genera in the database: 526 Anamorphic fungi (see p. 4), which are disseminated by propagules not formed from cells where meiosis has occurred, are presently not grouped by class, order, etc. Most propagules can be referred to as "conidia," but some are derived from unspecialized vegetative mycelium. A significant number are correlated with fungal states that produce spores derived from cells where meiosis has, or is assumed to have, occurred. These are, where known, members of the ascomycetes or basidiomycetes. However, in many cases, they are still undescribed, unrecognized or poorly known.

This research highlights the morphological and restriction analysis of three wild Agaricus species in Northern, Nigeria. A survey of mushrooms in Zaria, Nigeria was carried out within the months of May through October 2018. During the survey, Agaricus Silvicola, Agaricus alphitochrous and Agaricus diminitivus were encountered and their photographs were taken in their habitats using digital camera. Morphological descriptions and identifications of the three Agaricus species were carried out using mushroom field guides. Spore prints were collected and pure mycelia cultures were developed for genotyping. The genomic DNA of the Agaricus mushroom was extracted. Restriction digests using Mbo1, Saq 1 and Taq 1 showed different bandings patterns across the Agaricus species that revealed variation in the morphological characters of wild Agaricus species and this confirmed that the Agaricus species are new additions to the Nigerian mushroom biodiversity. Morphological and restriction digest of wild Agaricus have showed genetic relatedness that revealed taxonomic characters in the study that placed them in different species. The study may serve as baseline information for further studies on the taxonomy of other genera of mushrooms in Nigeria.
